Programming Information
Bit Name
Default
Bit No.
Type
This bit is valid in T1 DM format when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
= 0: Disable the 6 DDS pattern bits inversion.
= 1: All the 6 DDS pattern bits (‘0XX11101’) are inverted.
This bit is valid in ESF format when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
= 0: Disable the CRC-6 bits inversion.
= 1: All the 6 CRC bits are inverted.
In SF, T1 DM format, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
= 0: No Fs bit is inverted.
= 1: One Fs bit (the F-bit in even frame) is inverted.
In ESF format, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
= 0: No Frame Alignment bit is inverted.
= 1: One Frame Alignment bit is inverted.
In SLC-96 format, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
= 0: No Synchronization Fs bit is inverted.
= 1: One Synchronization Fs bit is inverted.
In SF, T1 DM, SLC-96 format, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
= 0: No Ft bit is inverted.
= 1: One Ft bit (the F-bit in odd frame) is inverted.
